Ok the tank is fixed. Sorry no pics. I did not have the camera with me. I first washed the tank out with the aluma-brite stuff. Cleaned the crack, fired up the Dynasty 300DX machine to 80 amps. The tanks are only .065 or so. I also backpurged the tank with pure argon for a while before I began to weld. As I got a puddle going the crack was migrating to the left and right like a bitch. It ended up being about a 11" long weld. Hooked up my pressure test jig and put 5 psi inside the tank. Shit, still a leak where I cannot even see a crack. Welded the bastard up some more. Re-pressure check and spray with soapy water, no leaks.
Good to go. Got the tank in the boat with the new vent lines and all -12AN fittings and lines going to the water/filter seperator. Just a few more things tol do on my list before I get it in the water again.

Crap TJ, I'm sorry to see this thread but knowing your craftsmanship, I'm betting we all think it's better now than it was even before your whoops.
Kinda reminds me of a bazillion years ago when I was a teenager, had a bare small block setting on the work table at home and set a head on the locating dowels without putting any bolts in, turned my head to grab something and that sumbitch popped off the pins and fell from the 4' landing right on my big toe........Note to the gang here, cast iron heads and toes don't mix. I smashed the shit out of it and didnt even crack the head.....

Sincerely........Fat-Toe Johnny
